LIQUID-FUEL-SUPPLYING APPARATUS:

Toall whom it may concern:

Be it known that I, Grocer. W. Warmer, a citizen of the United States, residing at 'Lapel, in the county of Madison and State of Indiana, have invented a new and useful 1 Liquid-Fuel-Supplying Apparatus, of which the following a specificatiomrefereuce being had" to the accompanying drawings, and to the letters and figures of reference marked thereon.

;This invention relates generally to governing means in connection with a pipe line for regulating the movement of liquid from a source of. supply to the terminal of the pipeline, the invention having reference more particularly to the supplying of engines of the'explosion type used on aut0m0- biles with liquid fuel from a "supply tank and controlling the movement of the fuel when pumped mm the tank.

object of the invention is to provide means whereby, when liquid fuel for supplying an automobile explosion engine is drawn from the supply tankby means of the engine, the supply shall be reliably and accurately regulated to the needs of the en ginewhether theautomobile' is moving on alevel road or up-hill or down-hill. 'An other object its to providehneans for controlling the supply of liquid fuel so as to permitgravity feed and to conveniently and economically make use of the engine suction for drawing the fuel from. a-supply tank,

more particularly when. the tank is at a Specification of Letters Patent. Patented Aug, 13, 1918,

In the drawings the numeral 1 indicates the automobile structure, 2 the explosion engine to be supplied with fuel, 3 theintake manifold through which the engine is sup plied withfuel, 4 the carburetor with which 4 the engine is provided for a well kno'wn purpose, and 5 a fuel supply tank carried by the automobile.

The bottom and jec'ts in view, the invention consists in imtop are firmly secured to the bodypart'of the proved apparatus for controlling the action ,rreceptacle by. means of bolts 10, 10'. The reof afipui nlp and also the delivery of liquid iceptacle is provided with a suitable device drawn by thepump from a suppl tank; whereby it may be supported on the auto- 1 ,the iinvention consisting further-in t e parts mobile, the top 8 preferably havin an up. a "in the combinations and arrangements wardly-extending arm 11 thereon-a. apted to 'rts as'hereiuafter particularly described be secured to the instrument board or dash further defined in the accompanying of the automobile. The bottom 6 has a nip- 5 ple 12 inserted therein upon which a check valve 13 is normall seabed and arranged in a valve cage 14 fixe on the top or inner por: tion of the bottom 6, and a pipe 15 is connected to the nipple and also to the supply tank 5 for conducting the liquid fuel to the receptacle. The bottom 6 has a valve casing 16 on its under side which has a bottom 17 having a neck 18 on its under-side, and a duct 19 extends through the bottom and the neck. A pi e 20 is connected to the neck and also to t e carbureter through which to supply the liquid fuel for the use of the engine. The upper or inner portion of the bottom 6 has an annular guide 21 thereon and the bottom has apertures 22therein' arranged around the uide to permit the liquid fuel to flow from t c receptacle to the valve casing below. The .under side of the bottom 6 has an'annular valve seat 23 thereon that extendsaround the series of apertures and within the valve casing 16. A suitable floatvalve 24 is provided which may be composed of cork or otherwise adapted to float in liquid, the valve having a flat top 25' adapted to have contact with the seat 23 to practically close the apertures 22. The valve is of such size to permit it to rise or fall slightly in the valve casing and it has a flat bottom 26 that may rest upon the bottom 17 of the casin the under side of the valve having radia grooves 27 to permit liquid to flow to the duct 19 when the valve is resting on the bottom of the casing. In operation the pipe 20 and the duct 19 may be filledwith t liquid fuel and also some fuel may remain in the valve casin so that the valve floats up to or nearly to t e seat 23, and when vacuum is created 1 the receptacle the valve is drawn to the seat to prevent fuel from being drawn back into the receptacle. Also when vacuum is created in the receptacle some of the liquid fuel is drawn into it from the tank 5 through the pipe 15 and prevented from returning by the action of the check valve 13.

p In order to create vacuum in the receptado a valve casing 28 is secured in a suitable aperture in the top 8 of the receptacle and has a duct 29 that extends from .the'interior of the casing to the interior of the receptacle, a valve stem 30 being provided which has screw threads 31 that are suitably fitted in the wall of the casing so that the stem is adjustable longitudinally, the inner end of the stem having a needle point valve 32 thereon adapted to partially close the duct 29. The valve stem is provided with a. lUL'k nut-33 that is seated on the outside of the casing, so that the valve shall be secured in position when properly adjusted to graduate the force of the suction produced by the engine and prevent excessive vacuum in the receptacle. the engine usually producing more suction than is required to draw the liquid fuel into the Il--(Q1')ttltfl0. pips is connected with the valve casing and the in take manifold 3 of the engine and afiords the necessary connection whereby to maintain the vacuum in the receptacle.

The vacuum in the receptacle is periodically changed in degree or fully destroyedautomatically to permit the flow of liquid from the receptacle to the carbureter, and for this purpose a suitable vent is rovided which preferably comprises a 0y indrical guide wall 35 fixed upon the t0p8 of the receptacle for guiding a valve, the top 8 having a port or duct 36 therein eentrally of the guide wall. A conical valve 37 is arranged in the guide wall and is normally seated by the force of gravity in the upper cndof the port 36 to permit vacuum to be created in the receptacle, the valve having an upwardly-extending shank portion '38 provided with guide wings 39 that extend outwardly beyond the valve to the guide wall, and the valve has a central socket bore 40 extending from the front of the valve and into the shank portion to receive an operating rod. The valve is retained in the guide wall by suitable means such as a cotter or other pin 41 inserted in the guide wall above the valve. The receptacle is provided with a'suitable float 42 whereby to control'the vent valve as the float ascends or descends with the fluctuating quantity of liquid in the receptacle. The float has a guide stem 43 on its bottom that extends into the guide 21 and has also on its top a guide stem 44 which constitutes a controlling element, a

'crosshead 45 being secured to the stem 14 bars being secured to the-top 8'of thereceptacle and extending downward toward the float; The upper portion ofthe stem 44 has aguide bore or socket 52 into which the rod 53 extends so to permit vertical movement of either the stem or the rdd relatively to the other, the upper port-ion of the rod 53 extending through the port 36 and into the bore 40 of the ventvalve inwh'u-h the rod may move vertically to a limited extent without moving the valve. The rod 53 has a controlling device which is preferably formed as a disk 54 fixed to the rotlso as to be above the stem 44. The glfidcbar 51 has a longitudinal slot 5;)

Hitach and is provided with a pivot 5 which extends across the slot and supports a. lri device vomn'isiu an arm 57 lhzit unrrlll' vtcmliufl st p tinger'fi thereon to runner lluguide but above ll\e lfit. Th
